BBT and ovulation

[Essex1512]

Hello, I normally ovulate around day 17/18 and this is confirmed by tracking my BBT. This month Fertility Friend app changed my ovulation date to day 21 which would make me 9DPO, however I still (I manually over-rid it) do believe it was day 17/18 going by EWCM and a few pains. Looking at my chart would you think the same?

I did a test today and BFN so I think im out for sure although I normally spot for a couple of days before my period which hasn't spotted yet.

Thoughts

Yep you ovulated day 17/18

@Plumchumm thank you, I thought as much! Think it was that drop at 21 that made FF change it all 🙄

@Essex1512 i had a drop 3dpo as well, it’s a secondary estrogen surge :)
good luck and baby dust!
